I have previously posted on roadrunners, terrestrial cuckoos found across the southwestern United States, from coast to coast (and south into central Mexico). Greater Roadrunners are monogamous, maintain long-term pair bonds, and mutually defend territories. Every spring pairs renew their bond through elaborate courtship desplays involving a lot of male dancing, including his bringing nesting material and food items to his mate (Hughes 2011),
As seen in the bottom photo, adults have prominent erectile crests and dark blue skin around their eyes. The orange postorbital apteria (the skin between the feather tracts) is usually not visible.
